I use this for my guitar, replacing one of the volume pots. Then the signal goes to the remaining volume pot, which now serves the mix from both pickups, and then on to the tone pot. Much more convenient for adjusting while playing.
Soldering was a challenge, as the space inside my guitar is very small, and so is this pot.
Excellent pot with a good feeling for the travel between end points and the dent for middle position, and with clear instructons for wiring.
I would have preferred this pot with a shorter and knurled shaft, though.
